I am using this addon all the time, works fine for me. I use multiple accounts and a combination of local and imap folders.
I have one problem only, if this could be solved, I'd be so grateful. By default I keep my message pane hidden (F8), so I open my mails in separate windows, by double-clicking them. Whenever I open an email, the message pane pops back on and I have to hide it again every time.
Is there a solution for this?
Keep up the good work
